I have connected a Ethernet cable(with DSL connection) from router to my computer ie a desktop computer(windows 7 32-bit) . But what happens is the connection is not identified "the diagnostics report stated that there is IP adress missing in LAN2 and in the toolbar what is displayed is "Unidentified Network no internet access". But if I connect the same cable in my laptop(windows 7 32-bit) I can access internet. what's the problem?
the network adapter of my desktop is "intel(R) PRO/100 VE Network Connection"
and of the laptop is "Realtek PCIe GBE Family Controller"
also in the desktop computer>device manager>modems>"the PCI modem is not working properly is displyed"
what shall I do to access internet on my desktop?
I would suggest that you uninstall and re-install your network adapter by using the device manager.
Then before you plug in the cable to the pc, restart your router making sure that no other devices are plugged in to it.
Once the router has restarted attach the cable to your pc and router and allow it a couple of minutes to detect the network and connect.
Note: Also make sure that your there isnt any issue of static/dynamic ip address conflict between your pc and the router i.e. router is set to DHCP on and your pc is set to dynamic ip address. You can check this by checking the ip settings on your laptop.
